| National Tree Benefit Calculator Web Service |
The Tree Benefit Calculator allows anyone to make a simple estimation of the benefits individual street-side trees provide. This tool is based on i-Tree's street tree assessment tool called STREETS. With inputs of location, species and tree size, users will get an understanding of the environmental and economic value trees provide on an annual basis.
The Tree Benefit Calculator is intended to be simple and accessible. As such, this tool should be considered a starting point for understanding trees' value in the community, rather than a scientific accounting of precise values. For more detailed information on urban and community forest assessments, visit the i-Tree website. |
